Behaviour of bentonite colloidal particles in aqueous system
Original language description
Smectite clays, such as bentonites, are considered as a primary ?buffer? material for isolating canisters containing high-level radioactive waste in many countries. However many experiments have proved that colloids may be formed during the interaction of bentonite with water. It is crucial to study the behaviour of these particles, because stable colloidal particles may affect the migration capability of radionuclides and the functionality of bentonite buffer may be significantly reduced. The aim of this research was to study the stability of bentonite colloids in aqueous system under various conditions. The effects of concentration of the electrolyte (NaCl), the type of the electrolyte (KCl, CaCl2, MgCl2) and bentonite saturation time on the stability of colloids were studied. Colloidal stability was investigated by conventional sedimentation tests. As a testing material was chosen Czech Sabenil bentonite, a sodium-activated type of bentonite.
